Description: Cells solitary or grouped in microscopic or macroscopic, irregular clusters, but not forming mucilaginous colonies; cells sometimes in short series of pseudofilamentous formations with 2-4 (20) cells. Mucilage absent or very fine, colourless, homogeneous, diffluent, around single cells. Cells long oval or cylindrical, sometimes several times longer than wide, straight, arcuate or sigmoid, 1.5 up to more than 20 um long and 0.4-6 (11) um wide, with parietal thylakoids; fine subunit arrays with p4 symmetry were found in few Synechococcus strains. Particularly in cultures there can arise long filamentous involution forms.

Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
